What are the benefits of multiprogramming?
using multiprogramming we can save the time multiprogramming resources to more than one current application i.e we can run multiple applications at a time that's way we refu…ses the time (MORE)

What is Monoprogramming and multiprogramming?
monoprogramming is when the memory can only process one program at a time were multiprogramming is when the memory can process more than one program

What are the differences between multitasking and multiprogramming?
Task is defined as a system program which consumes very less system resources(memory, CPU time, HD etc..). A task should have periodic activity and event based activity. Assum…e a printer which takes 10msec to print each line and you have fired a job to the printer.So the CPU should send every line with a 10msec gap. But transmitting a line to the printer is an output operation, which means the CPU has to execute some instrucions in order to transmit a line to the printer. Assume that the CPU takes 2usec to execute this. So this 2us is nothing but a sysem resource. So this is called as task since it is making less usage of system resource and it is periodic(every 10msec it has to execute instructions) and it is also event based(it has to check whether the printer is ON/OFF) Dos: Mutlitasking (can do printing and scanning simultaneously) but not multi programming(it can execute only one c/c++/java etc program in memory) Unix: Multiprograming and hence multi tasking. Multitasking and Multiprogramming: In multiprogramming, more than one program lies in the memory i.e. in terms of operating system, the schedular selects the jobs to be placed in ready queue from a number of programs. The ready queue is placed in memory and the existence of more than one program in main memory is known as multiprogramming. Example of multiprogramming, we open word, excel, access and other applications together but while we type in word other applications such as excel and access are just present in main memory but they are not performing any task or work. Or we can say that are not being used at the same time. Whereas multitasking means performing multiple tasks in parallel. Usually, CPU processes only one task at a time but the switching of CPU between the processes (also known as Context Switching) is so fast that it looks like CPU(or processor) is executing multiple processes at a time. Example of multitasking, we listen to music and do internet browsing at the same time (they execute parallely). Also a task (or process) is a part of program under execution. In other words, task is an active entity where as program is passive entity. (MORE)

What is multiprogramming and an example of multiprogramming?
Multiprogramming is a feature of an OS which allows running multiple programs simultaneously on 1 CPU. So, say, you may be typing in word, listening to music while in back…ground IE is downloading some file & anti-virus program is scanning. These all happen simultaneously to you. Actually programs don't run simultaneously, but OS divides time for each program according to priorities. When the chance of that program comes it runs, after the stipulated time is over, the next program runs & so on. Since this process is so fast that it appears programs are running simultaneously. Most of recent OSes are multiprogramming. For eg. Windows XP, Linux (MORE)

What is the difference between multiprogramming and batchprocessing?
Answer Multiprogramming is the act of writing programs that can be scheduled for running on more than one processor (either on a multiprocessor system, or in a cl…ustered environment such as MOSIX). Batch-Processing is when a certain set of programs are executed, in orderly form, with the results of one program typically being fed into the following program, without any interaction from the user -- as apposed to interactive programs which requires user input at certain stages in order for the program to continue. Batch-processing can also involve the use of multiprogrammed applications, provided they can be run in a non-interactive mode. (MORE)
